Plant the groundnuts in spring, ideally in a raised bed in light, well-draining soil. Provide the plants with a support since groundnuts have an upright vining habit. Keep the garden free of weeds to discourage pests but be gentle around the root ball of the tubers. Seedlings need at least two growing years and a minimum photoperiod of 14 hours to stimulate blooms. Harvest the tubers in the fall after the first frost has killed of the foliage.
